.... Accelerated corrosion occurs on the foreign line at the point of current discharge. The location of the discharge can be detected because the pipe-to-soil potential is very low at that point. Likewise in an oil or gas field, where the flowline system or the well casings from several wells are being...

..., they are basically useless in steam-heating systems. Similarly, methods for altering the internal environments in a steam-heating system to mitigate corrosion of the boiler, pipes, and heat exchangers should not be considered for corrosion control on the soil-side surfaces of the steel conduits and casings...
